PUNCHlNG-IVIACHINE.

Specification of Letters Patent.

Patented Feb. 27, 1906.

Application filed November 20, 1905. Serial No. 288,131.

To all whom it may concern.-

Be it known that I, JOHN A. BELL, a citizen of the United States, residing at Lathrop, in the county of San Joaquin, State of Califor- 5 nia, have invented certain new and useful Improvements in Punching-Machines and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to I which it appertains to make and use the same, reference being had to the accompanying drawings, and characters of reference marked thereon, which form a part of this specification.

I My invention relates to improvements in punching-machines; and my object is to produce such a machine as will enable a person to punch casin -iron, tank-iron, or similar ware readily and effectually and with foot or other power. This object I accomplish by providing an automatic spacer and by such other construction of parts as will appear by a perusal of the following specification and claims.

2 5 In the drawings similar characters of reference indicate corresponding parts in all the views.

Figure 1 is an end elevation of my improved device. Fig. 2 is a side elevation of the 0 same, partly broken out. Fig. 3 is a view taken on a line 90 a: of Fig. 2. Fig. 4 is a view taken on a line 'y y of Fig. 2. Fig. 5 is a view taken on a line 2 z of Fig. 2.

1 designates awork-bench, on top of which 3 5 is secured an iron plate 2, provided with a punch-die 3. Extending upward from the plate 2 are two standards 4, provided With projecting arms 5 and 6.

7 is a downwardly-projecting arm to which is pivoted a foot-lever 8, and 9 is a spring bearing between said lever and the under side of the bench 1.

10 is a rod pivotally mounted on the footlever 8 between the arm 7 and the spring 9 5 and extending upward through the table 1, plate 2, and arms 5 and 6. 11 is a similar rod extending through the arms 5 and 6 and provided with a unch 12, adapted to coact with the punch-ho e 3.

5o 13 and 15 are lugs forming component parts of the rod 10, and 14 is a similar lug forming a component part of the rod 11 and bearing snugly between the lugs 13 and 15.

16 is a guide provided with an overhanging arm or stripper 17.

18 is a p ate secured on the bench 1 in a line with the plate 2, said plate 18 being provided with a guide 19 and a groove 20, the guide 19 being in aline with the guide 16. In the groove 20 is a plate 21, provided with notches 22, disposed a distance apart equal to the distance desired between the holes punched in the material.

23 is a slot in the bench 1, opening into the slot 20 near the rear of the plate 21. 24 is an arm depending from the under side of the bench 1, to which is fulcrumed a link 25, connected at its other end to a lever 26,

which is fulcrumed to the foot-lever 8.

27 is a catch pivotally mounted on the link 25 and extending through the slot 23, and engaging with the notches 22 and 28 is a wire spring adapted to regulate the position of the said catch 27.

In using the machine the material to be punched is placed under the arm 17 and brought to bear against the end of the plate 21, the notches on which are arranged at the desired distance apart. The operator then presses the foot-lever 8 downward, and this causes the rod 10 to make a downward stroke, and the lug 13, bearing on the lug 14, causes the rod 11 to make a similar downward stroke, which action causes the required hole to be punched, as is apparent. The operator then releases his foot from the lever 8, and the spring 9 then pulls it into position again, which causes the rod 10 to resume its normal position, the lug 15 bearing on the lug 14 and causing the rod 11 to also resume its 0 normal position. The arm 17 acts as a stripper and prevents the material from rising with thepunching-rod 11. The downward stroke of the lever 8 pulls on the link 25, which action disengages the catch 27 from 5 the notches 22, and with the rise of the lever 8 the o erator bears the material against the head 0 the plate 21, which causes it to slip to the next notch 22, when the catch 27 again rises and engages with said notch, and the machine is again ready.

I have now entered into a detailed description of the present and preferred embodiment of my device. I do not desire, however, to confine myself to such specific detail, as such 10 5 modifications may be made in practice as fairly fall within the scope of my claims.

I claim as new and desire to secure by Letters Patent 1. In apunching-machine a bench, a plate 1 10 arranged on the top of said bench, two upwardly-extending standards on said plate,

two outwardly-extei'idin arms on said standards, a foot-lever secured to the under side of said bench, a spring located between said lever and the under side of said bench, a rod pivotally secured to said lever and extending upward through said bench, plate and arms, a punch-rod bearing in said arms and means for connecting said rods, as specified.

2. In apunching-nlachine the combination of a bench, an iron plate arranged on the top thereof and provided with a punch-die, two standards extending upward from said plate, two arms extending at right angles to said standards, a foot-lever secured beneath said bench, a spring located between said lever and the under side of said bench, a rod pivotally secured to said lever and extending upward through said bench, plate and arms, two outwardly-extending lugs forming component parts of said rod between said arms, a unch-rod bearing in said arms and adapted to coact with said die, and a lug forming a com onent part of said punch-rod and exten ing between said first-named lugs.

3. In a punching-machine the combination of a punching device, a spacer, consisting of a table, a slotted plate arranged on the top thereof, a slide-plate arranged in said slot and provided with notches at given distances apart, a slot in said table opening into said first-named slot, a lever fulcrumed to the under side of said table, a foot-lever secured to said table, a link connecting said foot-lever to In testimony whereof I affix my signature in presence of two witnesses.
